I do not understand, why they are overcomplicating things so much - why isn´t there just ONE rails framework? Issues with backwards compatibility vs. new features? Or what was causing this "forks"? In three years, will there be six rails versions?

If you have a large application, upgrading it will not be trivial. Suppose your company spent several months developing their app on Rails 3.1.x. Rails 3.2.x comes out and some gems you're using break when you try the upgrade. Your company still has other bugs to fix and features to produce, so they switch back to 3.1.x and just make a note to check compatibilities periodically.

The 3 versions patched are not forks. They're just different versions of Rails. In three years, they'll probably still support about 3 versions and drop support for older versions once they hit a certain age.

You can find the exact maintenance policy here: http://weblog.rubyonrails.org/2013/2/24/maintenance-policy-f...

Spot on. We were still running 3.0 a couple of months ago when a vulnerability came out with the indication that this would be the last patch version of 3.0. We made it a point to upgrade to Rails 3.1 right then—it took about two days, which we didn't really have, but we needed to do. Since then, we've taken another 3-4 days over the last couple of months to upgrade to 3.2 (and start using features that will make a migration to 4.0 much easier).

You mind if I ask what 3.2 features will make 4.0 migration easier? I haven't kept up with the 4.0 changes

We offer strong_paramters as a gem for Rails 3.2 apps, and generally tell anyone doing greenfield development to start with it to make the transition easier, and because it's simply better.

You can check the upgrading guide for more details about what's changed, and a third party is selling an ebook that has a ton of good info as well.

steveklabnik has it spot on. We're starting to move toward strong_parameters; we've got it as a gem, but we haven't yet made the change to entirely turn off attr_accessible.

We're also starting to use verb-matchers in the routes file, but that's going to be a bit more painful to deal with…

the rails community is not big on backwards compatibility, even within minor versions.
